Servicing them in an exercise in frustration as nothing is built very well and quite often the specs on components don't match up like bottom bracket spindles that are too long.

The brake pads are terrible and if they are not too hard they are so soft that they wear out in very short order.

They are built to the cheapest standard imaginable and if you have a little more time and a little more money I'd shop at a local bike shop or look for a decent used bike of better quality.
